WINDOW-CONTROL MECHANISM.

Applicationzfiled February a, 1924. Serial no. 691,347.

To all whom, it may concern) Be it known that I, ANGELO Ronnn'r CLAS,

a citizen of the United States, and a resident of Toledo, in the'county of Lucas and State of Ohio, have invented a new, and useful Window-Control Mechanism, which 'invenin its construction and is capable of beingeasily and quickly "installed as a unit, in a door or window frame.

Further objects and advantages of the.

invention will be apparent from the following' detailed description thereof. While the invention in its broader aspect is capable of embodiment in numerous forms, two embodiments only thereof are illustrated in the accompanying drawings, in which,

Figure 1 is a fragmentary view of a closed vehicle door equipped with one form of the invention and with the window member shownin lowered position. Fig. 2 is an enlarged section on the line 22 in Fig. 1 with parts in full. Fig. 3 is a fragmentary section on the line 33 in Fig. 2. Fig. 4: is a view similar to Fig. 1 with thedoor equipped with a slightly different form of the invention and with the window in partly lowered position. Fig. 5 is an enlarged fragmentary section on the line 55 in Fig. 4. Fig. 6 is a section on the line 66 in Fig. 5. Fig. 7 is a fragmentary view similar to Fig. ,3 with the inner end of the spring attached t0v the segment and its outer end attached to the bracket plate, andFig. 8 is a section on the line 88 in Fig. 7,

Referring to the drawings, .1 designates a door or window frame of the type commonly used in closed motor vehicles and having the window opening 2 in its upper portion adapted to be'closed by a glass or window member 3, which when open lowers into a well 4 provided in the frame 1 below the opening 2. The frame 1 is provided with the customary, lock-board 5 at the. inner side of the upper ortion of the well 1.

In the embo' iment of the invention, shown :in Figs-1, 2 and 3, 1 designates a bracket or be y late which is rigidly secured to the inner si e of the lock-board 5 by screws 7, or in any other suitable manner, and is of oblong .form projecting, in the present instance, at its lower end below the lock boardf5. This plate is preferably composed of light stock, and in order to add strength is provided with a depressed longitudinally extending portion 8. A pivot stud 9 is fixedly mountedin the lower end portion of the plate 6 below the lower edge of the lock- HEISSUED oard 5 and has one end projectingfrom the plate in opposition to the lock-board 5 and forming a'journal on whi h a segmental gear 10 is mounted for free gurning movements. The gearlO is preferably stamped from sheet metal and lies fiat at its inner side against the plate 6, being retained on the stud 9, in the present instance, by a fiangingof the stud.

An arm 11, ;which is also preferably stamped from sheet metal, projects radially from the gear segment 10, being fixed at one-end to one end'portion of the-segment and having its opposite or free end provided with a roller 12 on which the lower edge of the "glass or window member 3 rests. It is apparent that raising and lowering movements of the arm 11, upon, a turning the segment 10, will eflect or permit corresponding raising and lowering movements.

of the glass or window member 3, and that the roller 12 will travel a distance along the lower edge of the window member during such movements. A guard 13 projects from the lower edge of the glass or window member 3 and underlies-the roller 12 to nection with which t e control means is, to

be used. The adjustment of the arm is taken care of by providing a 'plurality' of sets of holes 14in the segment 10 through which the securing rivets 15 of. the arm may be projected. V In the present instance,

in the plate 30 above the pivot 33 and profour sets of holes 1 1 are provided, two sets jects outward therefrom through the lockin radially spaced relation at one end of the segment, and two in radially spaced relation at the center portion of the segment.

The drive means for the segment 10 comprises a pinion 16, which meshes with the teeth of the segment and is carried by a shaft 17 that is journaled for turning movements in the upper end portion of the plate 6. The shaft 17 projects out through an opening 18 in the lock-board 5 and receives an operating handle 19 at its outer end. The enlargement 20 on the shaft 17 e11- closes a locking mechanism which has nothing to do with the present invention and need not, therefore, be described. The outer side of the pinion 16 with respect to the plate 6 is flanged to lap the edge of the segment 10 and serve to retain such segment in flat engagement with the side of the plate 6, or, in other words, to prevent an outward bending of the segment from engagement with the drive pinion.

Inorder to counterbalance the weight of the window member 3, the control means includes a coiled spring 21 of the clock or convolute type, which is mounted on an end of the stud shaft 9 at the opposite side of the plate 6 to the segment 10 and has its inner end fixed against turining to said shaft. The spring 21 lies flat against the adjacent side of the plate 6, in the present instance, below the lock-board .5 and within the confines or outer edgesof the segment 10 and has its outer end attached to a pin 22 on the enlarged hub portion 23 of the segment 10. For the purpose of adjusting the tension of the spring 21, the pin 22 is adapted to be placed in any one of a series of holes 24, provided in spaced relation in the hub portion 23 concentrically of its center. In Figs. 7 and 8 the pivot Stud 9 is shown as fixed to the segment 10 instead of to the bracket plate 6, so that the inner end of the spring 21 is attached to the segment, while the outer end of the sprin is adjustably attached to the plate 6 by tl ie pin 22 being inserted in one of a series of holes 21 in the plate.

In the form of the invention illustrated in Figs. 4, 5 and 6, 30 designates the bracket plate, which is preferably of thin sheet metal and secured to the inner side of the lock-board 5 by screws 31, or in any other suitable manner, with its lower end projecting below the lock-board. The window member operating arm 32 is mounted for free turning movements on a pivot 33 secured to the lower portion of the plate 30, and the arm has a segmental set of gear teeth 34 formed on its upper edge in concentric relation to the swinging axis of the arm. The segmental pinion 35 is mounted on an operating shaft 36 which is journaled board 5 and carries an operating handle 37 at its outer end. The pinion 35 1s flanged to overlap the meshing portion of the segment 34 to retain the latter-in engagement therewith. In this form of the invention, the segments 34 and 35 are of the same size so that a partial turning of the operating handle 37 will impart a full throw to the arm 32,- whereas in the form of the invention first described several turns of the operating handle are required for the same purpose. A convolute or clock type of spring 38 is used, it being mounted on an extended end of the pivot 33 at the opposite side of the plate 30 to the arm 32 and having its outer or free end attached to a pin 39 on the arm 32.

It is apparent that in both forms of the invention, the control device is composed of a minimum number of parts and that the entire unit construction may be extremely light and inexpensiveto manufacture and adapted to be mounted in a small space. It is also evident that the form and manner of mounting the spring adds to the efficiency and compactness of the' device and is an important feature.

The first form of the invention is used on higher class jobs than the second form and also where the space in which the control handle is operated is limited, as the first form requires a much shorter operating handle than the second form.

I wish it understood that my invention is not limited to any particular construction, arrangement or form of the arts as it is capable of numerous 'modi cations and changes without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:
